It was 50 year ago this coming Thursday, June 1, that The Beatles’ trailblazing album Sgt. Pepper’s Lonely Hearts Club Band was officially released in the U.K., one day before it hit stores in the U.S. To mark the milestone, a special celebration will take place at the Capitol Records tower in Los Angeles.

The commemorative event, dubbed “Pepper Day,” will begin at 9:09 a.m. PT on Thursday with the raising of a specially designed Sgt. Pepper’s flag on top of the tower. Doing the honors will be the Sgt. Pepper character from Cirque du Soleil’s Beatles-themed Las Vegas production LOVE. In addition, the building will be adorned with variety of themed decorations, including special signs and an inflatable Sgt. Pepper’s drum above the tower’s Vine Street entrance.

Adding to the festivities, starting at sunset on Thursday, the roof of the Capitol Records building will be illuminated with lights corresponding to the four colors of the suits that The Beatles wore on the Sgt. Pepper’s album cover.
